Graph API to set "send as" permission on Office 365 group mailbox

Viewed 18

I did try to research a lot but couldn't find it. I have to set "send as permission" for some users in an Office 365 group mailbox. I have an Office 365 group created and I need to assign the "send as" permission to some users in a group via API. I didn't find this information in the Microsoft documentation. Do we have any other way to make this automated?

As of September 2022, this cannot yet be done through Microsoft Graph. Your only option for automation is to use Exchange PowerShell's Add-RecipientPermission cmdlet:

Add-RecipientPermission "Help Desk" -AccessRights SendAs -Trustee "Ayla Kol"
